Samsung RF22A4221SR/AA refrigerator water filter: HAF-QIN
Samsung identifies the refrigerator as RF22A4221SR/AA and publishes HAF-QIN / HAF-QIN/EXP as a compatible water-filter family for RF22A4221 models. This record remains intentionally narrowed to the exact RF22A4221SR/AA appliance while adding Samsung's own HAF-QIN replacement and model-dependent filter-indicator reset guidance.
Safety boundary
- Samsung's HAF-QIN replacement procedure starts by turning off the refrigerator water supply.
- Do not force a filter that does not seat or lock normally; use the exact model manual or Samsung support if the housing, filter, or connection behaves differently than documented.
- If the housing or connection leaks, stop and address the leak before continued use.
Compatibility requires a direct model listing, explicit supersession, or equivalent manufacturer evidence.
Required identifiers
- Complete refrigerator model: RF22A4221SR/AA
- Filter family: HAF-QIN
- Package/SKU may appear as HAF-QIN/EXP
Compatibility rules
- Use this record only for the exact Samsung RF22A4221SR/AA model boundary.
- Samsung's official HAF-QIN filter listing includes RF22A4221 model-family fit; verify the complete model suffix on the appliance label before ordering.
- HAF-QIN/EXP is the current Samsung package/SKU naming shown on the official filter page.
Never assume
- Do not infer compatibility from similar cabinet size, door style, or an RF-prefix alone.
- RF18A5101 and RF20A5101 remain outside this exact-model page's scope. Samsung's current HAF-QIN product page separately lists those families, but this record makes no appliance-specific claim about them.
Selection boundary
- Appliance in this record: Samsung RF22A4221SR/AA
- Filter family: HAF-QIN
- Samsung package/SKU: HAF-QIN/EXP
- RF18A5101 and RF20A5101 are outside this page's exact-model scope even though Samsung's HAF-QIN product page separately lists those model families
Samsung HAF-QIN replacement steps
- Turn off the refrigerator water supply.
- Open the filter cover, rotate the old HAF-QIN filter counterclockwise to unlock it, and remove it.
- Remove the protective cap from the new filter, insert it into the housing, and turn clockwise until it locks.
- Align the filter's LOCK symbol with the indicator line.
- Samsung says the filter-indicator reset method varies by refrigerator interface; use the exact model manual or Samsung's model-appropriate reset path rather than assuming one control sequence.
